1. Irrelevant personnel are not allowed to enter the construction site. 2. Safety helmets, protective glasses, labor protection suction, work shoes and rubber gloves must be worn. It is a safety violation for the constructors not to wear the labor protection supplies, and it is normal to have punching. It is also an unforeseen and uncontrollable phenomenon. There are many reasons for punching, roughly as follows:
1) The operator does not operate properly, the operating time is too long, including the medicine has been heated and gassed because it is still filling, etc., the filling is not dense, there is an air barrier, etc.;
2) Improper temperature control. When the temperature is high, the mixing agent, the borehole wall temperature is not properly controlled, and the amount of inhibitor agent is not enough, causing the agent to react too quickly, etc.;
3) Improper hole layout design; hole spacing and low resistance line are too large;
4) Improper selection of the drill bit, and the hole diameter is too large;
5) The hole wall is smooth and so on. The temperature of the medicament is high and corrosive during punching, and it may cause serious damage to the cornea if it enters the eye. In order to prevent injury accidents, operators must wear labor protection products such as shock-proof and dust-proof PVC labor insurance glasses produced in accordance with national safety standards for operation.
3. Before the medicine is poured into the borehole until the rock cracks, the face should not directly face the borehole filled with medicine. After the medicament is filled, cover it with a sack or brown mat and keep it away from the filling point. More care should be taken when observing the development of the fissure. In addition, the construction site should be specially prepared with water and towels. When piercing the holes, the medicine splashed into the eyes and on the skin should be rinsed with water immediately. Severe pro-photographers should be sent to the hospital for cleaning and treatment immediately.
4. It is necessary to change and control the response time during the construction of the crushing project. Inhibitors or triggers must be added in accordance with the regulations, and formulated and used as required. It is strictly forbidden to add any other legal articles without authorization.
5. It is strictly forbidden to add the crushing agent into a perforated container (into straight glass, beer bottle, etc.), otherwise it is very dangerous.
6. If the hole wall temperature is higher for the drilled hole and the hole that has just been flushed, it is determined that the temperature is normal and meets the requirements and can be cleaned before continuing to charge.
7. The crushing agent should be moisture-proof and anti-exposure in the process of allowing and storing. It should be used immediately after opening. If the bag has not been used up in sequence, the bag opening should be tightened immediately, and then opened when necessary.
8. Before using the crushing agent, please make sure that the operator has read and understood the instructions carefully.
